IMPROVEMENT IN CIDER-MILLS- @llgt Srljrttlt nfrmh it in time 51m stun amt making gym if the same.

TO ALL' WHOM-I'll MAY CONCERN? Be it known that I, J. l). WILLOUGHBY, .ofiShippensburg, in the county of Cumberland, and State of Penn: sylvanin, have invented certain new and use 111 Improvements in Mills forExtraotiug the Juice of Fruits; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to. the accompanying drawings, making partof this specification, and to the lett s of reference marked thereon, like letters indlcating like parts wherever they occur. 1 I

To enable others skilled in the art to construct and use my invention, Iwill proceed todescribe it.

My, invention consists in constructing a. mill with grinding-rolls for crushing or'grinding the fruit, and a series of elastic pressing-rolls for pressing out-the juice, and so arranged that the operation of both grinding and pressing shall proceed simultaneously.

Figure 1. is atrnnsverse vertical section.

Figure'2 is a t'ront view of a portion.

A represents one end of the frame, which may be of any required size and form. In'the upper portion of the frame is located a hopper, H, for receiving the fruit and feedingit to the grinding-rolls B, which may be of any suitable style. Immediately below tho.griudingrolls I place two pressing-rolls, 0, one ofwhich should be mounted in adjustable bearings, (as indicated in dotted lines in fig. 1,) which is operated by a set-screw, E, for adjusting these rolls, so that they may be pressed together, and made to run tight against each other. These rolls .0 are made of wood or metal, and covered with rubber or similar elastic material, the object being to receive the pomace or crushed fruit as it falls from the-grinding-rolls, nnd, while squeezing out the juice, which will run 03' at each end, be sufiicieutly elastio to permitthe pomade or seeds to pass through between the rolls B, the pressing process being similar to that of the clothes-winger. Under the ends of these rolls B are placed troughs a, to catch the juice and conduct it into the reservoir provided to receive it. In order to prevent thejuice from adhering and running backlon the under side of the rolls, Iplace a. piece of springs or other absorbing material at the ends of the rollers, as indicated by S, which rests in the spout a, and conducts the juice from the rolls thereto. If -desire d, the rolls may be so inclined as to cause the juice to flow oil from the rolls all at one end. In order to prevent the pomsoe' from adhering to the rollers and 'being oarried around with them, I arrange scrapers n underneath the rollers, as shown in fig. 1. Those scrapers n are pivoted at their lower edges, as

indicated at o, and are connected by a link, at, to a spring-rod, m, which keeps their upper edges in contact with.

the surface of the rollers, as shown in fig.- 2. By this. means the pomace is scraped off from the rolls B, and drops down upon the rdllers D, by which it is again pressed. Any number of rolls may be thus arranged to press it successively. I I

I When it is desired to'add water to the 'pomace after it has been pressed,'for the purpose of producing-a liquid for making vinegar, as is customary in cider-mills,a spout, e, may be arranged to convey the water to the upper side of the last pair of rolls, where it will saturate the pomaco, and, when squeezed. therefrom,will flow ofl'at the'ends into the spouts e,'fron 1 whichit will flow into the vessels placed to receive it, and thus the entire process may be performed at one operation.

It-will be understood that the rolls will be so connected by gearing or otherwise, as to cause thein torevolve in the proper direction, the gearing in this case being indicated by the red lines in fig.

' This machine is specially adapted for eigtracting the juice of grapes and berrios, and, when used for this ur ose, it may be desirable to substitute, for the grinding-rolls B, simnle crushing-rolls; slightly roughened or ribbed on their surface.

Ialso find it desirable to make the surface of the pressing-rolls slightly rough, in order to cause them to more readily seize hold of thepomace, especially if the rolls be of small diameter. -It is obvious that but one of the pressing-rolls in each pair needs to he covered with elastic material, and that, if desired, instehd of placing thehopper and grinding-rolls over the pressing-rolls, they may be located elsewhere, and the ground material be conveyed to the pressing-rolls by an endless apron or belt.

Having thus described my invention, what I claim, is- The arrangement of the grinding-rolls B'rslatively with one or moi-c 'pairs of pressing-rolls, C D, and the spoutsfor receiving and conveying separatelythe various qualities of juice produced, su stantially as shown (1 d 'b d.
